Weird. I found this but at the end, the command doesn't help me. I'm not sure why. It does talk about using LUKS on top of LVM causing this problem. Since the fix doesn't work, is this a different problem?? https://linux-blog.anracom.com/tag/device-still-in-use/ I've tried every command I can find and it still shows busy. I even restarted udev and lvm. Still busy. Ideas? Dale :-) :-)
